Extra shows during extra hours?

[JanaV]

We're going to WDW in December and I'm trying to plan our days. Wondering if we should plan around the extra hours. Does anyone know if they add extra shows during these extra hours? Dd loves the Beauty and the Beast show in MGM, Lion King in AK and now there's a new Nemo show in AK - are there shows going on during the extra magic hours?

Thanks much!
